JOHN J. SOHILLINGER, OF NEW YORK, N. Y.

FIRE-PROOF BUILDING.

SPECIFICATION forming part of Letters Patent No. 233,029, dated October 5, 1880.

Application filed March 4, 1880.

(No model.)

To all whom it may concern:

Be it known that l, JOHN J. SGHILLINGER, a citizen ofthe United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Fire-Proof Buildings, ot' which the following is a specification.

his invention relates to the construction of ceilings in a fire-prooi' building, which are made of a layer of serving' to imite a series ot' hollow tiles which are supported by the floor-beams, and which are made in sections united together, as hereinafter more fully explained.

This invention is illustrated in the accompanying drawings, in which- Figure l represents a vertical section in the plane .r x, Fig. 4. Fig. 2 is a similar section inthe plane y y, Fig. 4. Fig. 3 is a similar section in the plane'z z, Fig. 4. Fig. 4 is a plan 01 top view on a smaller scale than the previousgures. Fig. 5 is an inverted plan on the same scale as Fig. 4.

Similar letters indicate corresponding parts.

In the example shown in the drawingsthe letters A A designate the Hoor-beams, which serve to support the floors and ceilings in the building.

In forming my improved ceiling I proceed as follows: Beneath the floor-beams AA, at a distance of about an inch (more orless) from their lower surfaces, I place a board or platform, B, and on this platform I adjust the four hollow tiles C C C" C, the form of which is fully illustrated in the drawings, Fig. l

showing longitudinal sect-ions of two of said tiles, Fig. 3 showing end views, Fig. 4 showing top views ot' four such tiles, one being shown partly in section; and Fig. 5, bottom views or inverted plans of four such tiles. From these figures it will be seen that each of these tiles has a flat bottom, c, and a convex top, b, an inclined closed edge, c, two cavities, d d, which open on the inside and are separated from each other by a partition, c, Fig. 4, and shoulders fj", the object ot' which will be presently more fully explained.

The inclined edges cof the several tiles C cement cast against and I O O O are placed at a distance ot' about four inches (more or less) from the beams A A; and between the tiles O O", and also between the tiles C O, are placed concave shells D D', respectively, (see Figs. 2 and 4,) which rest upon the shoulders f j" of the tiles, and are provided with inclined flanges g g', corresponding to the inclined edges c ot' the tiles, and of such a depth that their bottom edges rest upon the platform B, as shown in Fig. 2.

After the tiles O O O OW and the shells have been thus adjusted I cast upon the platform B, and between edges c g of the tiles and the beams A A, a layer, E, ot' cement, which fills the spaces between the inner edges of the tiles G O C O" and between the iianges g g of the shells D D, and which is increased in depth beams and the tiles, as shown i 2, to form the skewbacks It 7L.

After the layer E has been cast in I place between the tiles C G C 0 and the shells D D' curved tiles F, Figs. 1, 2, 3, and 4, which rest upon the shoulders j' j" of the hollow tiles O O O OW; and in order to complete the arch between the beams A A the spaces between the curved tiles F and the hollow tiles O O O O and the shells D D', respect` ively, are tilled out with cement, lead, or other suitable material, as shown in Figs. l and 2.

After the layer E has set the platform B is removed and the ceiling is ready. At the same time the arches formed by the combi nation of t-he hollow tiles C C O C, the shells D D, the curved tiles F, and the layer E form a firm support for the licor above. Furthermore, the arches produced by this combination have a continuous air-space, so that the floor above can be conveniently and uniformly heated by introducing into the airspaces of the several arches heated air or any other equivalent heating medium.

The cement which I use, by preference, for the layer E consists of gypsum, lime, and cinders, or hydraulic cement and sand 5 or any other composition of a similar nature may be used 5 or the layer E may be formed of dat plates made of clay and burned, which are between the n Figs. l and (see Fig. 5,)n

placed between the tiles. The tiles may also In testimony whereof I have hereunto Set be made ot' clay and burned, or of cement, as my hand and seal in the presence of two sub- Io above stated. scribing Witnesses.

What I claim as new7 and desire to secure l v JOHN J SGHILLINGER [L s l 5 by Letters Patent, is-
